Engineering Contradictions & Design Principles
Engineering Contradiction Analysis
1Measurement precision
If accelerated testing is performed until the inspection target reaches limit state, then life estimation can be obtained, but test time becomes considerably long
Solution Approach 1:
The patent applies preliminary action by performing non-destructive imaging at multiple time points during the accelerated test to capture state changes before the limit state is reached. By acquiring images at regular intervals and tracking feature amount changes, the system can predict remaining life based on the progression rate of defects, eliminating the need to wait until actual failure occurs.
Solution Approach 2:
The patent replaces traditional mechanical/physical testing methods with non-destructive X-ray imaging and computational analysis. Instead of physically testing until failure, the system uses imaging to detect and quantify internal defect changes, substituting physical degradation observation with non-contact detection and prediction algorithms.
2Ease of operation
If human sensory evaluation is used for life estimation, then evaluation can be performed, but subjective judgment variations occur and accuracy is lowered
Solution Approach 1:
The patent replaces human sensory evaluation with automated non-destructive imaging and computational analysis. The system uses X-ray imaging to objectively detect and quantify internal defect features, eliminating subjective human judgment. The automated extraction of feature amounts from images provides consistent, reproducible measurements that do not vary between evaluators.
Solution Approach 2:
The patent creates a quantitative copy of the inspection target's internal state through non-destructive imaging. By capturing and analyzing the internal structure at multiple time points, the system creates a digital record that can be objectively measured and compared, replacing subjective human observation with objective data reproduction and analysis.
3Ease of manufacture
If traditional life estimation methods are used, then evaluation can be performed, but no quantifiable index is provided for life estimation
Solution Approach 1:
The patent replaces qualitative human evaluation with quantitative imaging analysis. By extracting measurable feature amounts from X-ray images and tracking their changes over time, the system generates objective, quantifiable indices for life estimation. This substitution of manual evaluation with automated measurement provides precise numerical data that can be used for prediction and decision-making.
